Comparison of Silicone Adhesives in Skin Contact Applications: How Material Properties Influence Performance & Wear

Stephanie Steichen, Technical Service & Development Specialist for Healthcare Materials, Dupont

Abstract: Silicone adhesives are widely used in a variety of medical applications, including wound care dressings, scar care treatments, medical device attachment and in transdermal drug delivery. DuPont has developed several different types of silicone adhesives designed to perform in these varied applications. The primary performance objective for these adhesives is their reliable and secure adhesion to skin. However, the skin is a highly variable substrate that is difficult to fully recreate in a lab. This presentation will explore a variety of alternative and complementary techniques to evaluate these adhesives, including peel adhesion to stainless steel and polycarbonate substrates, tack, penetration testing, rheology and moisture vapor transmission (MVTR).
